Find a better way to reset the refresh timer

At the moment, to reset the refresh timer bar, the CSS animation gets disabled, then the width is set to zero. In order to start the timer, the animation is enabled and then the timer is set to the full value.

The problem comes about that if you don't add a delay before starting the timer (after resetting it to zero), the timer will just stay at the maximum width and won't animate.

There is probably a more reliable way of doing the reset timer that doesn't involve timer delays. So, find a better way to reset the refresh timer.
